Detailed Implementation

[0070] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0071] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0072] The cleaning system 100 according to an embodiment of this application is described below with reference to the accompanying drawings.

[0073] As shown in Figures 1 to 3, the cleaning system 100 according to an embodiment of this application includes a cleaning base station 20 and a cleaning device 10. The cleaning device 10 and the cleaning base station 20 are detachably coupled. When the cleaning device 10 and the cleaning base station 20 are coupled, the cleaning base station 20 delivers cleaning fluid to the cleaning device 10. Therefore, the cleaning fluid delivered by the cleaning base station 20 to the cleaning device 10 can enhance the cleaning power of the cleaning device 10, thereby improving the cleaning effect of the cleaning system 100.

[0074] According to the embodiments of this application, the cleaning system 100 can enhance the cleaning power of the cleaning equipment 10 by delivering cleaning fluid to the cleaning equipment 10 through the cleaning base station 20, thereby improving the cleaning effect of the cleaning system 100.

[0075] According to some embodiments of this application, the cleaning device 10 includes a liquid storage tank 11, a mopping component 12, and a delivery pump 13. The mopping component 12 is used to clean the surface to be cleaned. The delivery pump 13 is connected to the liquid storage tank 11 and is used to deliver cleaning liquid from the cleaning base station to the liquid storage tank 11 and to deliver cleaning liquid from the liquid storage tank 11 to the mopping component 12. That is, the liquid storage tank 11 is used to store cleaning liquid. During the cleaning process of the cleaning device 10, if the mopping component 12 contacts the surface to be cleaned and is movable relative to the surface to be cleaned so as to remove dirt from the surface to be cleaned by friction of the mopping component 12, the delivery pump 13 can deliver the cleaning liquid from the liquid storage tank 11 to the mopping component 12 to wet the mopping component 12. The mopping component 12, which is wetted with cleaning liquid, can more effectively remove dirt from the surface to be cleaned, thereby improving the cleaning effect and cleaning efficiency of the cleaning device 10. When the cleaning fluid in the storage tank 11 is depleted, the cleaning device 10 can move to the replenishment point, which refers to the storage location of the cleaning fluid at the cleaning base station. The storage tank 11 is connected to the cleaning fluid storage location at the cleaning base station, and the cleaning fluid from the cleaning base station is delivered to the storage tank 11 via the delivery pump 13. This ensures that the cleaning fluid in the storage tank 11 can be continuously delivered to the mopping component 12 to clean the surface to be cleaned. This improves the integration of the delivery pump 13, reducing its number and thus the number of parts in the cleaning device 10. This simplifies the structure of the cleaning device 10 and reduces its manufacturing cost. It also allows for a smaller overall size, improving the device's throughput and expanding its applicability.

[0076] The cleaning solution can be water, a cleaning agent for cleaning surfaces such as floor cleaner, or a mixture of cleaning agent and water. There are no specific restrictions on the type of cleaning solution. Furthermore, the cleaning solution for the cleaning base station can be stored in the cleaning base station 20, which is detachably connected to the cleaning device 10. The cleaning device 10 can replenish the cleaning solution by returning to the cleaning base station 20. The cleaning solution for the cleaning base station can also come directly from a tap water pipe, etc. There are no specific restrictions on the type of cleaning solution used.

[0077] In a specific example, the transfer pump 13 is a diaphragm pump, which enables the transfer pump 13 to transport a variety of different media, such as liquids and gases, while having good sealing performance to prevent leakage of the transported media.

[0078] According to some embodiments of this application, as shown in Figures 2 to 4, the cleaning device 10 has a replenishment mode and a cleaning mode. In the replenishment mode, the delivery pump 13 delivers the cleaning fluid from the cleaning base station to the storage tank 11 and stops delivering the cleaning fluid to the mopping component 12. In the cleaning mode, the delivery pump 13 delivers the cleaning fluid from the storage tank 11 to the mopping component 12 and stops delivering the cleaning fluid from the cleaning base station to the storage tank 11. Thus, the cleaning device 10 can replenish the cleaning fluid in the storage tank 11 in the replenishment mode, while avoiding waste caused by delivering the cleaning fluid to the mopping component 12. After replenishing the storage tank 11, the cleaning device 10 can continue cleaning the surface to be cleaned. In the cleaning mode, the delivery pump 13 delivers the cleaning fluid to the mopping component 12, allowing the mopping component 12, which is soaked in the cleaning fluid, to more effectively remove dirt from the surface to be cleaned. This ensures a better cleaning effect and efficiency of the cleaning device 10 in the cleaning mode.

[0079] According to some embodiments of this application, the cleaning device 10 includes: a first pipeline assembly and a second pipeline assembly. The first pipeline assembly is connected to both a liquid storage tank 11 and a delivery pump 13 for delivering cleaning fluid from the cleaning base station to the liquid storage tank 11. The second pipeline assembly is connected to both the liquid storage tank 11 and the delivery pump 13 for delivering cleaning fluid from the liquid storage tank 11 to the mopping component 12. In other words, the first pipeline assembly can form a liquid channel connecting the cleaning fluid storage area of ​​the cleaning base station and the storage tank 11. Driven by the delivery pump 13, the cleaning fluid of the cleaning base station can enter the storage tank 11 through the portion of the first pipeline assembly connecting the cleaning fluid storage area and the storage tank 11 to replenish the storage tank 11 with cleaning fluid. The second pipeline assembly can form a liquid channel connecting the storage tank 11 and the installation area of ​​the mop 12. Driven by the delivery pump 13, the cleaning fluid in the storage tank 11 can be delivered to the mop 12 through the portion of the second pipeline assembly connecting the storage tank 11 and the installation area of ​​the mop 12 to wet the mop 12.

[0080] Therefore, by cooperating with the first pipeline assembly, the delivery pump 13 can replenish the cleaning fluid into the storage tank 11, and by cooperating with the second pipeline assembly, the delivery pump 13 can deliver the cleaning fluid to the mop 12. That is, by cooperating with the first pipeline assembly and the second pipeline assembly, the needs of replenishing the cleaning fluid and wetting the mop 12 can be met, which can improve the integration of the delivery pump 13 and reduce the number of delivery pumps 13.

[0081] According to some embodiments of this application, the first pipeline assembly includes a liquid inlet pipeline 141, an air extraction pipeline 142, and an exhaust pipeline 143. One end of the liquid inlet pipeline 141 is connected to the liquid storage tank 11, and the other end forms a mating interface 1411. One end of the air extraction pipeline 142 is connected to the liquid storage tank 11, and the other end is connected to the inlet of the delivery pump 13. The exhaust pipeline 143 is connected to the outlet of the delivery pump 13. The mating interface 1411 is used to connect with the storage location of the cleaning fluid in the cleaning base station. For example, the mating interface 1411 can mate with the mating connector 2333 of the liquid supply tank 22 of the cleaning base station 20, or the mating interface 1411 can be directly connected to a tap in a water pipe, etc., without specific limitations. In other words, when replenishing the liquid in the storage tank 11, the interface 1411 is connected to the storage location of the cleaning fluid in the cleaning base station. That is, one end of the liquid inlet pipe 141 is connected to the storage location of the cleaning fluid in the cleaning base station, and the other end is connected to the storage tank 11. Thus, a liquid channel can be formed between the storage location of the cleaning fluid in the cleaning base station and the storage tank 11 through the liquid inlet pipe 141. The two ends of the air extraction pipe 142 are connected to the storage tank 11 and the inlet of the delivery pump 13, respectively. Thus, an airflow channel can be formed between the storage tank 11 and the delivery pump 13 through the air extraction pipe 142. The delivery pump 13 is connected between the air extraction pipe 142 and the exhaust pipe 143. Driven by the delivery pump 13, the gas in the storage tank 11 can be discharged sequentially through the air extraction pipe 142, the delivery pump 13 and the exhaust pipe 143.

[0082] Therefore, when it is necessary to replenish the cleaning fluid in the storage tank 11, after the interface 1411 is connected to the storage location of the cleaning fluid in the cleaning base station, the gas in the storage tank 11 can be continuously discharged through the delivery pump 13, the air extraction pipe 142 and the exhaust pipe 143. As the gas in the storage tank 11 is discharged, the gas pressure in the storage tank 11 also decreases. That is, the delivery pump 13 performs a negative pressure operation on the storage tank 11 to form a pressure difference between the storage location of the cleaning fluid in the cleaning base station and the storage tank 11. This allows the cleaning fluid in the cleaning base station to flow into the storage tank 11 through the inlet pipe 141 under the action of the pressure difference, so as to realize the operation of replenishing the liquid in the storage tank 11.

[0083] The second piping assembly includes a liquid extraction pipe 151 and a liquid discharge pipe 152. One end of the liquid extraction pipe 151 is connected to the storage tank 11 and the other end is connected to the inlet of the delivery pump 13. The liquid discharge pipe 152 is connected to the outlet of the delivery pump 13. In other words, both ends of the liquid extraction pipe 151 are connected to the storage tank 11 and the inlet of the delivery pump 13, respectively. Thus, a liquid channel can be formed between the storage tank 11 and the inlet of the delivery pump 13 through the liquid extraction pipe 151. The delivery pump 13 is connected between the liquid extraction pipe 151 and the liquid discharge pipe 152. Therefore, driven by the delivery pump 13, the liquid in the storage tank 11 can be sequentially transported to the mopping component 12 through the liquid extraction pipe 151, the delivery pump 13, and the liquid discharge pipe 152 to realize the operation of delivering cleaning fluid to the mopping component 12.

[0084] The connection point between the suction pipe 142 and the storage tank 11 is the first connection point, and the connection point between the liquid extraction pipe 151 and the storage tank 11 is the second connection point. The first connection point is higher than the second connection point. In other words, the position where the gas in the storage tank 11 is discharged from the storage tank 11 through the suction pipe 142 is higher than the position where the cleaning liquid in the storage tank 11 is discharged from the storage tank 11 through the liquid extraction pipe 151. Therefore, setting the position where the gas in the storage tank 11 is discharged from the storage tank 11 through the suction pipe 142 (the first connection point) at a relatively high position can prevent the cleaning liquid in the storage tank 11 from being extracted during the negative pressure extraction process. Furthermore, setting the position where the cleaning liquid in the storage tank 11 is discharged from the storage tank 11 through the liquid extraction pipe 151 (the second connection point) at a relatively low position can better ensure that the cleaning liquid in the storage tank 11 is completely drained, avoiding waste or contamination caused by residual cleaning liquid in the storage tank 11.

[0085] In one specific example, one end of the drain line 152 is connected to the outlet of the delivery pump 13, and the other end of the drain line 152 is located above the mop 12 and opens downward, so that cleaning fluid can be sprayed from above the mop 12 onto the mop 12 through the drain line 152.

[0086] According to some embodiments of this application, the first connection position is located at the upper end of the storage tank 11, and the second connection position is located at the lower end of the storage tank 11. The delivery pump 13 applies negative pressure to the storage tank 11 through the suction pipe 142, allowing the cleaning fluid from the cleaning base station to enter the storage tank 11 under pressure differential. When the liquid level in the storage tank 11 is higher than the first connection position, the cleaning fluid in the storage tank 11 will be extracted through the suction pipe 142. That is, the first connection position is the highest point at which the delivery pump 13 and the first pipe assembly can deliver cleaning fluid into the storage tank 11. Therefore, by setting the first connection position at the upper end of the storage tank 11, the amount of cleaning fluid delivered by the delivery pump 13 and the first pipe assembly into the storage tank 11 can be increased. In other words, the delivery pump 13 and the first pipe assembly can ensure that the cleaning fluid from the cleaning base station roughly fills the storage tank 11, thereby avoiding waste of storage space in the storage tank 11 and improving the endurance of the cleaning equipment 10.

[0087] In addition, the second connection position is located at the lower end of the storage tank 11, that is, the position where the cleaning liquid in the storage tank 11 is discharged from the storage tank 11 through the liquid extraction pipe 151 is located at the lower end of the storage tank 11. In this way, the cleaning liquid in the storage tank 11 can be drained completely with the cooperation of the delivery pump 13 and the liquid extraction pipe 151, so as to avoid the cleaning liquid remaining in the storage tank 11, causing waste or dirt.

[0088] In a specific example, the first connection position is located at the top of the liquid storage tank 11. Therefore, when the liquid level in the liquid storage tank 11 has not reached the top of the liquid storage tank 11, the cleaning fluid of the cleaning base station can continuously flow into the liquid storage tank 11 under the action of the delivery pump 13 and the air extraction pipeline 142 drawing negative pressure into the liquid storage tank 11 until the liquid level in the liquid storage tank 11 reaches the top of the liquid storage tank 11. This can avoid the waste of storage space in the liquid storage tank 11 and achieve high utilization.

[0089] According to some embodiments of this application, the connection position between the liquid inlet pipe 141 and the liquid storage tank 11 is a third connection position, which is lower than the first connection position. Specifically, the connection position between the liquid inlet pipe 141 and the liquid storage tank 11 is where the cleaning fluid for cleaning the base station enters the liquid storage tank 11. In other words, the position where the cleaning fluid for cleaning the base station enters the liquid storage tank 11 through the liquid inlet pipe 141 is lower than the position where the gas inside the liquid storage tank 11 is discharged from the liquid storage tank 11 through the exhaust pipe 142. Therefore, it is possible to avoid extracting the cleaning fluid from the liquid storage tank 11 during the process of creating a negative pressure inside the liquid storage tank 11, and also to avoid wasting the storage space inside the liquid storage tank 11.

[0090] In some embodiments, both the first connection position and the third connection position are higher than the highest liquid level in the storage tank 11. That is, when the cleaning fluid in the storage tank 11 reaches the highest liquid level, the position where the inlet pipe 141 delivers the cleaning fluid into the storage tank 11 and the position where the delivery pump 13 draws air from the storage tank 11 are still above the liquid surface. This prevents the delivery pump 13 from drawing out the cleaning fluid from the storage tank 11 and reduces the resistance of the inlet pipe 141 in delivering the cleaning fluid into the storage tank 11.

[0091] In some embodiments, both the first connection position and the third connection position are located at the top of the storage tank 11. This ensures that while the cleaning fluid for the cleaning base station fills the storage tank 11 under the negative pressure created by the delivery pump 13, the connection position of the inlet pipe 141 to the storage tank 11 is also located at the top of the storage tank 11. This means that the inlet pipe 141 does not need to overcome the resistance of the cleaning fluid within the storage tank 11 to enter it. This reduces the resistance to the cleaning fluid entering the storage tank 11 through the inlet pipe 141, thus reducing the energy consumption of the delivery pump 13 in delivering the cleaning fluid to the storage tank 11.

[0092] According to some embodiments of this application, the connection position between the liquid inlet pipe 141 and the liquid storage tank 11 is a third connection position, which is higher than the second connection position and located at the upper part of the liquid storage tank 11. That is, the position where the cleaning fluid of the cleaning base station enters the liquid storage tank 11 through the liquid inlet pipe 141 is higher than the position where the cleaning fluid in the liquid storage tank 11 is discharged from the liquid storage tank 11 through the liquid extraction pipe 151. Therefore, by setting the position where the cleaning fluid for cleaning the base station enters the storage tank 11 through the inlet pipe 141 at a relatively high position, the cleaning fluid in the storage tank 11 can be prevented from obstructing the entry of the cleaning fluid for cleaning the base station through the inlet pipe 141 into the storage tank 11. This reduces the resistance of the cleaning fluid for cleaning the base station into the storage tank 11 through the inlet pipe 141, which helps to reduce the energy consumption of the delivery pump 13 in delivering the cleaning fluid for cleaning the base station to the storage tank 11. By setting the position where the cleaning fluid in the storage tank 11 is discharged through the extraction pipe 151, i.e., the second connection position, at a relatively low position, it can be better ensured that the cleaning fluid in the storage tank 11 can be completely drained, so as to avoid the waste or dirt caused by the cleaning fluid remaining in the storage tank 11.

[0093] According to some embodiments of this application, the connection position between the inlet pipe 141 and the storage tank 11 is the third connection position, which is located on the same side of the storage tank 11 as the first connection position. That is, the location where the gas in the storage tank 11 is discharged from the storage tank 11 through the exhaust pipe 142 and the location where the cleaning fluid of the cleaning base station enters the storage tank 11 through the inlet pipe 141 are located on the same side of the storage tank 11. Therefore, the interval between the location where the gas in the storage tank 11 is discharged from the storage tank 11 through the exhaust pipe 142 and the location where the cleaning fluid of the cleaning base station enters the storage tank 11 through the inlet pipe 141 can be shortened. In other words, the location where negative pressure is applied to the storage tank 11 is brought closer to the location where the cleaning fluid of the cleaning base station enters the storage tank 11, thereby improving the negative pressure application effect of the delivery pump 13 at the third connection position. This increases the pressure difference between the storage location of the cleaning fluid in the cleaning base station and the third connection position, which is beneficial for improving the efficiency of the cleaning fluid entering the storage tank 11.

[0094] According to some embodiments of this application, the distance L between the first connection position and the third connection position satisfies: 0 < L ≤ 100 mm. That is, the distance between the position where the gas in the storage tank 11 is discharged from the storage tank 11 through the suction pipe 142 and the position where the cleaning liquid of the cleaning base station enters the storage tank 11 through the inlet pipe 141 is controlled within the range of 0 to 100 mm. For example, the distance between the position where the gas in the storage tank 11 is discharged from the storage tank 11 through the suction pipe 142 and the position where the cleaning liquid of the cleaning base station enters the storage tank 11 through the inlet pipe 141 can be: 5 mm, 8 mm, 10 mm, 20 mm, 30 mm, 40 mm, 60 mm, 80 mm, 100 mm, etc., and no specific limitation is made here. Therefore, it avoids the situation where the cleaning fluid of the cleaning base station enters the storage tank 11 through the inlet pipe 141 and is directly sucked away by the exhaust pipe 142 due to the small distance between the first and third connection positions. At the same time, it avoids the situation where the large distance between the first and third connection positions affects the negative pressure effect of the exhaust pipe 142 at the third connection position. Thus, it can ensure the negative pressure value at the point where the cleaning fluid of the cleaning base station enters the storage tank 11 while preventing the cleaning fluid entering the storage tank 11 through the inlet pipe 141 from being sucked into the exhaust pipe 142. The layout is reasonable.

[0095] According to some embodiments of this application, the air extraction pipeline 142 is provided with a first control valve 144, which is used to control the opening and closing of the air extraction pipeline 142. In other words, the first control valve 144 can control the opening of the suction pipe 142 to form a gas channel between the storage tank 11 and the delivery pump 13. Under the action of the delivery pump 13, the gas in the storage tank 11 can be discharged sequentially through the suction pipe 142, the delivery pump 13 and the exhaust pipe 143 to create negative pressure in the storage tank 11, so that the cleaning fluid of the cleaning base station can enter the storage tank 11 under the action of pressure difference. The first control valve 144 can also control the cutting off of the suction pipe 142, that is, to cut off the connection between the delivery pump 13 and the storage tank 11 through the suction pipe 142, so as to avoid the suction pipe 151 being unable to draw the cleaning fluid in the storage tank 11 due to the opening of the suction pipe 142 and the delivery pump 13 drawing out the gas in the storage tank 11, thereby ensuring the stability of the delivery of cleaning fluid to the mopping component 12.

[0096] Specifically, when the cleaning fluid of the cleaning base station is delivered to the storage tank 11 by the delivery pump 13 in cooperation with the first pipeline assembly, the first control valve 144 controls the air extraction pipeline 142 to be opened; when the cleaning fluid in the storage tank 11 is delivered to the wiping component 12 by the delivery pump 13 in cooperation with the second pipeline assembly, the first control valve 144 controls the air extraction pipeline 142 to be cut off.

[0097] According to some embodiments of this application, a cleaning base station 20, which is suitable for detachable cooperation with the cleaning device 10, is provided with a trigger 21. When the cleaning device 10 and the cleaning base station 20 are in cooperation, the interface 1411 is connected to the cleaning base station 20, and the trigger 21 triggers the first control valve 144 to open the suction pipe 142. That is, when the liquid storage tank 11 needs to be replenished, after the cleaning device 10 returns to the cleaning base station 20 and the interface 1411 is connected to the cleaning base station 20, the first control valve 144 can be automatically controlled to open the suction pipe 142 through the cooperation of the trigger 21 and the first control valve 144. That is, after the interface 1411 is connected to the cleaning base station 20, there is no need to separately control the first control valve 144 to open the suction pipe 142. At this time, the liquid storage tank 11 forms a gas channel with the delivery pump 13 through the suction pipe 142. The delivery pump 13 can draw negative pressure from the liquid storage tank 11 through the suction pipe 142 to make the cleaning base station... The cleaning fluid from the station can enter the storage tank 11 under pressure differential. After the storage tank 11 is replenished, if the liquid level in the storage tank 11 reaches the preset level, the cleaning equipment 10 can separate from the cleaning base station 20 to continue cleaning operations. The trigger 21's effect on the first control valve 144 disappears, and the first control valve 144 cuts off the suction line 142. That is, after the cleaning equipment 10 leaves the cleaning base station 20, there is no need to separately control the first control valve 144 to cut off the suction line 142, so that the cleaning fluid in the storage tank 11 can be transported to the wiping component 12 through the suction line 151, the delivery pump 13, and the drain line 152. Thus, the step of separately controlling the first control valve 144 to open or close the suction line 142 can be eliminated, which is beneficial to improving the automation level of the first control valve 144 and reducing the control difficulty of the first control valve 144.

[0098] According to some embodiments of this application, the first control valve 144 and the interface 1411 are located on the same side of the cleaning device 10. This reduces the difficulty of coordinating the interface 1411 and the first control valve 144 with the cleaning base station 20.

[0099] As shown in Figures 5 and 6, according to some embodiments of this application, the first control valve 144 includes a valve core 1441, which is movable between an on position and a off position. That is, when the valve core 1441 is in the on position, the first control valve 144 opens the suction line 142; when the valve core 1441 is in the off position, the first control valve 144 cuts off the suction line 142. The movable nature of the valve core 1441 between the on and off positions allows the first control valve 144 to open and close the suction line 142.

[0100] When the cleaning device 10 and the cleaning base station 20 are engaged, there is an interaction force between the trigger 21 and the valve core 1441, driving the valve core 1441 to move to the open position. When the cleaning device 10 and the cleaning base station 20 are disengaged, the valve core 1441 is in the cut-off position. That is, when the trigger 21 is not engaged with the valve core 1441, the valve core 1441 is usually in the cut-off position. Specifically, when the trigger 21 does not trigger the first control valve 144, the first control valve 144 is usually in the position of cutting off the air extraction pipeline 142. When the trigger 21 engages with the valve core 1441 and exerts a force on the valve core 1441, the valve core 1441 moves from the cut-off position to the open position, thereby opening the air extraction pipeline 142. Therefore, by cooperating with the trigger 21 and the valve core 1441, the function of automatically opening the air extraction pipeline 142 when the cleaning equipment 10 and the cleaning base station 20 are working together can be well realized, and the function of automatically cutting off the air extraction pipeline 142 when the cleaning equipment 10 and the cleaning base station 20 are separated can be realized. This can eliminate the step of separately controlling the first control valve 144 to open or cut off the air extraction pipeline 142, which is conducive to improving the automation level of the first control valve 144 and reducing the control difficulty of the first control valve 144.

[0101] According to some embodiments of this application, the first control valve 144 includes an elastic reset member 1442. One end of the elastic reset member 1442 is connected to the air extraction pipeline 142 and the other end is connected to the valve core 1441. The elastic reset member 1442 is used to drive the valve core 1441 to move to the cut-off position. That is, the elastic reset member 1442 has a tendency to drive the valve core 1441 to move toward the cut-off position. Therefore, when the cleaning device 10 is separated from the cleaning base station 20, the force between the trigger member 21 and the valve core 1441 disappears, and the valve core 1441 is held in the cut-off position under the action of the elastic reset member 1442 to cut off the air extraction pipeline 142. When the cleaning device 10 is engaged with the cleaning base station 20, the force between the trigger member 21 and the valve core 1441 drives the valve core 1441 to overcome the elastic force of the elastic reset member 1442 and move from the cut-off position toward the conduction position to open the air extraction pipeline 142. Therefore, the elastic reset member 1442 can reset the valve core 1441, which is in the conducting position, to the cut-off position after the cleaning equipment 10 is separated from the cleaning base station 20. This can effectively save the operation of resetting the valve core 1441 separately, which is conducive to improving the automation level of the first control valve 144 and reducing the control difficulty of the first control valve 144.

[0102] According to some embodiments of this application, when the cleaning device 10 and the cleaning base station 20 cooperate, there is a magnetic force between the trigger 21 and the valve core 1441 to drive the valve core 1441 to move to the conducting position. That is, when the cleaning device 10 and the cleaning base station 20 cooperate, the magnetic force between the trigger 21 and the valve core 1441 drives the valve core 1441 to squeeze the elastic reset member 1442 toward the trigger 21, thereby realizing the movement of the valve core 1441 from the cut-off position to the conducting position to open the suction pipe 142; after the cleaning device 10 and the cleaning base station 20 are separated, the magnetic force between the trigger 21 and the valve core 1441 disappears, that is, the force acting on the valve core 1441 to squeeze the elastic reset member 1442 toward the conducting position disappears, and the valve core 1441 moves from the conducting position to the cut-off position under the thrust of the elastic reset member 1442 restoring its deformation and cuts off the suction pipe 142. Therefore, by using the magnetic cooperation between the trigger 21 and the valve core 1441, the difficulty of the trigger 21 controlling the first control valve 144 to open or close the air extraction pipeline 142 can be reduced. At the same time, the structure is simple, the reliability is high, and the investment cost is low.

[0103] According to some embodiments of this application, the exhaust pipe 143 and the drain pipe 152 are the same pipe. That is, only one exhaust pipe 143 or one drain pipe 152 needs to be installed. The gas delivered by the delivery pump 13 and the cleaning fluid delivered by the delivery pump 13 can be delivered to the mop 12 simultaneously through the exhaust pipe 143 or the drain pipe 152. As a result, the pipe cost can be saved, and the installation space occupied by the exhaust pipe 143 or the drain pipe 152 can be saved.

[0104] According to some embodiments of this application, a second control valve is provided on the exhaust pipe 143. The second control valve is used to control the opening and closing of the exhaust pipe 143. That is, the second control valve can control the opening of the exhaust pipe 143, so that when the delivery pump 13 draws negative pressure into the liquid storage tank 11 through the suction pipe 142, the gas drawn from the liquid storage tank can be discharged through the exhaust pipe 143; the second control valve can control the closing of the exhaust pipe 143, so that when the delivery pump 13 draws cleaning liquid from the liquid storage tank 11 through the suction pipe 151, the cleaning liquid drawn by the delivery pump 13 can only be delivered to the mopping component 12 through the drain pipe 152, which can prevent the cleaning liquid from flowing out through the exhaust pipe 143 and affecting the wetting effect on the mopping component 12.

[0105] According to some embodiments of this application, the first pipeline assembly includes a first pipeline and a second pipeline. One end of the first pipeline is connected to the inlet of the delivery pump 13 and the other end forms a mating interface 1411, wherein the mating interface 1411 is used to dock with the storage location of the cleaning fluid of the cleaning base station. One end of the second pipeline is connected to the outlet of the delivery pump 13 and the other end is connected to the storage tank 11. A third control valve is provided on the first pipeline for controlling the opening and closing of the first pipeline. A fourth control valve is provided on the second pipeline for controlling the opening and closing of the second pipeline. The second pipeline assembly includes a third pipeline and a fourth pipeline. One end of the third pipeline is connected to the inlet of the delivery pump 13 and the other end is connected to the storage tank 11. The fourth pipeline is connected to the outlet of the delivery pump 13. A fifth control valve is provided on the third pipeline for controlling the opening and closing of the third pipeline. A sixth control valve is provided on the fourth pipeline for controlling the opening and closing of the fourth pipeline.

[0106] In other words, the delivery pump 13 can be connected to the cleaning fluid storage location of the cleaning base station through the first pipeline, and the delivery pump 13 can be connected to the storage tank 11 through the second and third pipelines. The delivery pump 13 can also deliver cleaning fluid to the wiping component 12 through the fourth pipeline. Among them, the first, second, third, and fourth pipelines can all be independently controlled to be turned on or off. Thus, by controlling the on or off of the first, second, third, and fourth pipelines, a single delivery pump 13 can deliver the cleaning fluid from the cleaning base station to the storage tank 11 and the cleaning fluid in the storage tank 11 to the wiping component 12, which helps to simplify the structure of the cleaning equipment 10.

[0107] Specifically, when it is necessary to replenish the liquid in the storage tank 11, after connecting the interface 1411 to the storage location of the cleaning liquid in the cleaning base station, the third control valve is controlled to open the first pipeline, the fourth control valve is controlled to open the second pipeline, the fifth control valve is controlled to cut off the third pipeline, and the sixth control valve is controlled to cut off the fourth pipeline. Thus, under the drive of the delivery pump 13, the cleaning liquid in the cleaning base station can only be delivered to the storage tank 11 in sequence through the first pipeline, the delivery pump 13, and the second pipeline. When it is necessary to deliver the cleaning liquid in the storage tank 11 to the wiping component 12, the third control valve is controlled to cut off the first pipeline, the fourth control valve is controlled to cut off the second pipeline, the fifth control valve is controlled to open the third pipeline, and the sixth control valve is controlled to open the fourth pipeline. Thus, under the drive of the delivery pump 13, the cleaning liquid in the storage tank 11 can only be delivered to the wiping component 12 in sequence through the third pipeline, the delivery pump 13, and the fourth pipeline.

[0108] As shown in Figures 2 to 7, the cleaning base station 20 includes a liquid supply tank 22. The cleaning device 10 is adapted to be detachably coupled with the cleaning base station 20. When the cleaning device 10 is coupled with the cleaning base station 20, the delivery pump 13 is used to deliver the cleaning liquid in the liquid supply tank 22 to the storage tank 11. That is, the cleaning base station 20 stores the cleaning liquid through the liquid supply tank 22. When the cleaning liquid in the storage tank 11 is exhausted, the cleaning device 10 can move to the cleaning base station 20 and couple with it. Through the connection between the storage tank 11 and the liquid supply tank 22, the delivery pump 13 delivers the cleaning liquid in the liquid supply tank 22 to the storage tank 11 for storage. This ensures that after the cleaning device 10 is separated from the cleaning base station 20, the cleaning liquid in the storage tank 11 can be continuously delivered to the mopping component 12 to clean the surface to be cleaned, thus better ensuring the cleaning endurance of the cleaning device 10. Therefore, the integration of the delivery pump 13 can be improved to reduce the number of delivery pumps 13, that is, to reduce the number of parts of the cleaning equipment 10, which helps to simplify the structure of the cleaning equipment 10 and reduce the manufacturing cost of the cleaning equipment 10. At the same time, it is easy to reduce the overall size of the cleaning equipment 10 to improve the throughput of the cleaning equipment 10 and to broaden the applicable scenarios of the cleaning equipment 10.

[0109] According to some embodiments of this application, the cleaning base station 20 includes a liquid supply pipe 23 and a functional component 24. One end of the liquid supply pipe 23 is connected to a liquid supply tank 22, and the functional component 24 is disposed in the liquid supply pipe 23. When the cleaning device 10 cooperates with the cleaning base station 20, the other end of the liquid supply pipe 23 is detachably connected to a liquid storage tank 11. The delivery pump 13 is used to deliver the cleaning liquid in the liquid supply tank 22 to the liquid storage tank 11 through the liquid supply pipe 23. The functional component 24 is configured to control the liquid supply tank 22 to stop supplying liquid to the liquid supply pipe 23 and control the cleaning liquid in the liquid supply pipe 23 to flow into at least one of the liquid storage tank 11 and the liquid supply tank 22 when the liquid level in the liquid storage tank 11 reaches a preset liquid level.

[0110] In other words, after the cleaning equipment 10 and the cleaning base station 20 work together, the liquid supply tank 22 can be connected to the liquid storage tank 11 through the liquid supply pipe 23. That is, the liquid supply pipe 23 can form a connecting flow channel between the liquid supply tank 22 and the liquid storage tank 11, so that the cleaning liquid in the liquid supply tank 22 can be driven to enter the liquid storage tank 11 through the liquid supply pipe 23 under the action of the delivery pump 13, thereby realizing the liquid replenishment operation of the liquid storage tank 11. When the liquid level in the storage tank 11 reaches the preset level, and it is no longer necessary to continue supplying cleaning fluid to the storage tank 11, the functional component 24 controls the supply tank 22 to stop supplying liquid to the supply pipe 23, which prevents the cleaning fluid in the storage tank 11 from overflowing. Furthermore, the functional component 24 controls the cleaning fluid in the supply pipe 23 to flow into at least one of the storage tank 11 and the supply tank 22, i.e., to clean the cleaning fluid in the supply pipe 23 to avoid residual cleaning fluid. This prevents residual cleaning fluid from flowing out through the end of the supply pipe 23 away from the supply tank 22 after the cleaning device 10 is separated from the cleaning base station 20, thus avoiding waste or environmental pollution. In addition, when the end of the supply pipe 23 away from the supply tank 22 is in a lower position, draining the residual liquid in the supply pipe 23 prevents the residual liquid from forming a siphon effect, thus avoiding waste caused by the supply pipe 23 continuously draining the cleaning fluid from the supply tank 22 under a siphon effect.

[0111] According to some embodiments of this application, the other end of the liquid supply pipe 23 has a connector 2333 suitable for corresponding to the cleaning device 10. The position of the connector 2333 is lower than the bottom surface of the liquid supply tank 22. That is, the liquid supply tank 22 is located above the connector 2333, so that sufficient space can be reserved below the liquid supply tank 22 for the cleaning device 10 to enter the cleaning base station 20, so as to facilitate cleaning and other operations of the cleaning device 10 in the cleaning base station 20. Furthermore, the connector 2333 is located below the bottom surface of the liquid supply tank 22, which facilitates the docking of the connector 2333 with the cleaning device 10. For example, the connector 2333 can be at approximately the same height as the cleaning device 10, which helps to reduce the difficulty of docking the cleaning device 10 with the connector 2333.

[0112] According to some embodiments of this application, as shown in Figures 2 to 4, the cleaning system 100 has a replenishment mode, a residual liquid discharge mode, and a cleaning mode. In the replenishment mode, the cleaning device 10 cooperates with the cleaning base station 20, the delivery pump 13 operates, and the functional component 24 does not operate. At this time, the supply tank 22 is connected to the storage tank 11 through the supply pipe 23. Driven by the delivery pump 13, the cleaning liquid in the supply tank 22 enters the storage tank 11 through the supply pipe 23, thereby realizing the replenishment operation of the storage tank 11. In the residual liquid discharge mode, the cleaning device 10 cooperates with the cleaning base station 20, and the functional component 24 operates. At this time, the supply pipe 23 is still connected to the storage tank 11, but the cleaning liquid in the supply tank 22 stops flowing into the storage tank 11 through the supply pipe 23. The functional component 24 operates to control the flow of the cleaning liquid in the supply pipe 23 into at least one of the storage tank 11 and the supply tank 22, thereby preventing the residual cleaning liquid in the supply pipe 23 from flowing out or causing waste due to siphon effect. In cleaning mode, the cleaning device 10 is separated from the cleaning base station 20. After being separated from the cleaning base station 20, the cleaning device 10 can continue to clean the surface to be cleaned. During this process, the delivery pump 13 delivers the cleaning liquid in the storage tank 11 to the mopping component 12 to improve the cleaning effect and cleaning efficiency.

[0113] According to some embodiments of this application, the cleaning device 10 includes a liquid level sensor disposed inside the liquid storage tank 11. When the cleaning device 10 cooperates with the cleaning base station 20, the functional component 24 is electrically connected to the liquid level sensor. The liquid level sensor can accurately obtain the liquid level of the cleaning fluid in the liquid storage tank 11. Therefore, during the process of supplying cleaning fluid to the liquid storage tank 11 through the supply pipe 23 from the supply tank 22, when the liquid level in the liquid storage tank 11 reaches a preset level, since the functional component 24 is electrically connected to the liquid level sensor, the liquid level sensor can transmit a signal indicating that the liquid level in the liquid storage tank 11 has reached the preset level to the functional component 24. After receiving the signal, the functional component 24 switches to the working state and cleans the cleaning fluid in the supply pipe 23. Thus, through the cooperation of the liquid level sensor and the functional component 24, a control signal can be promptly transmitted to the functional component 24 after the cleaning fluid in the liquid storage tank 11 reaches the preset level, which helps to improve the automation level of the cleaning system 100.

[0114] According to some embodiments of this application, the functional component 24 includes: a first pump body 241 connected to a liquid supply pipe 23. The first pump body 241 is configured to deliver gas into the liquid supply pipe 23 when the liquid level in the storage tank 11 reaches a preset liquid level, so that the liquid supply tank 22 stops supplying liquid to the liquid supply pipe 23 and the cleaning liquid in the liquid supply pipe 23 flows into at least one of the storage tank 11 and the liquid supply tank 22. That is, when the liquid level in the storage tank 11 reaches the preset liquid level, the gas delivered into the liquid supply pipe 23 by the first pump body 241 can push the cleaning liquid in the liquid supply pipe 23 toward the storage tank 11 and / or the liquid supply tank 22 to empty the cleaning liquid in the liquid supply pipe 23. Therefore, by using gas to drive the liquid flow, the cleaning fluid in the supply pipe 23 is emptied, which is low-cost and can better avoid introducing other types of liquid into the supply pipe 23, thus improving the reliability of the first pump body 241 in cleaning the cleaning fluid in the supply pipe 23.

[0115] According to some embodiments of this application, in the residual liquid discharge mode, the delivery pump 13 does not operate. That is, when the cleaning liquid in the supply pipe 23 is cleaned by the first pump body 241, the delivery pump 13 stops driving the cleaning liquid in the supply tank 22 to be transported to the storage tank 11 through the supply pipe 23. As a result, it can be better avoided that the gas transported to the supply pipe 23 by the first pump body 241 by the delivery pump 13 will enter the storage tank 11 through the supply pipe 23. This can also prevent the storage tank 11 from being in a negative pressure state, which would allow the cleaning liquid in the supply tank 22 to still enter the storage tank 11 through the supply pipe 23. In other words, it can be better avoided that the delivery pump 13 affects the first pump body 241 in discharging the residual liquid in the supply pipe 23, which is beneficial to improving the discharge effect of the functional component 24 on the cleaning liquid in the supply pipe 23.

[0116] According to some embodiments of this application, in the residual liquid discharge mode, the transfer pump 13 operates, and the operating power of the transfer pump 13 is less than the operating power of the first pump body 241. Here, "the operating power of the transfer pump 13 is less than the operating power of the first pump body 241" means that the amount of gas that the transfer pump 13 can extract per unit time is less than the amount of gas that the first pump body 241 can deliver per unit time. Therefore, the transfer pump 13 can only pump a portion of the gas delivered by the first pump body 241 to the liquid supply pipe 23 into the liquid storage tank 11, thereby driving the cleaning liquid located between the gas input position of the first pump body 241 and the liquid storage tank 11 in the liquid supply pipe 23 into the liquid storage tank 11. The remaining gas delivered by the first pump body 241 to the liquid supply pipe 23 can drive the cleaning liquid located between the air input position of the first pump body 241 and the liquid supply tank 22 in the liquid supply pipe 23 into the liquid supply tank 22, thus achieving the cleaning of residual liquid in the liquid supply pipe 23.

[0117] According to some embodiments of this application, the cleaning base station 20 includes a cleaning component and a cleaning tank 25. The cleaning component includes a second pump body 242, which is connected to a liquid supply tank 22 to deliver cleaning liquid in the liquid supply tank 22 to the cleaning tank 25. The cleaning liquid is then delivered to the mopping component 12 of the cleaning equipment 10 in the cleaning tank 25 by the second pump body 242, such as removing mud and dirt that the mopping component 12 picks up during the cleaning of the surface to be cleaned, thereby improving the cleaning effect of the cleaning equipment 10 on the surface to be cleaned.

[0118] The first pump body 241 and the second pump body 242 are the same pump body. The cleaning system 100 also has a cleaning mode. In the cleaning mode, the first pump body 241 rotates forward to deliver the cleaning liquid in the supply tank 22 to the cleaning tank 25, so as to clean the mop 12 located in the cleaning tank 25. In the residual liquid discharge mode, the first pump body 241 rotates in reverse, and the second pump body 242 rotates in reverse to deliver gas into the supply pipe 23 to clean the cleaning liquid in the supply pipe 23. Therefore, by integrating the functions of delivering cleaning liquid into the cleaning tank 25 and delivering gas into the supply pipe 23 into the first pump body 241, the integration of the first pump body 241 can be improved and the second pump body 242 can be saved. This reduces the number of parts in the cleaning base station 20, simplifies the structure of the cleaning base station 20, and reduces the manufacturing cost of the cleaning base station 20.

[0119] In a specific example, the first pump body 241 is a peristaltic pump, which enables the first pump body 241 to transport various media, such as liquids and gases, while ensuring the accuracy and stability of the first pump body 241 and operating with low noise.

[0120] According to some embodiments of this application, as shown in Figures 1 to 7, the cleaning base station 20 includes a liquid supply tank 22, a liquid supply pipe 23, and a functional component 24. One end of the liquid supply pipe 23 is connected to the liquid supply tank 22, and the functional component 24 is disposed in the liquid supply pipe 23. The cleaning device 10 is detachably coupled with the cleaning base station 20 and includes a storage tank 11. When the cleaning device 10 and the cleaning base station 20 are coupled, the other end of the liquid supply pipe 23 is detachably connected to the storage tank 11. The cleaning liquid in the liquid supply tank 22 is suitable for being transported to the storage tank 11 through the liquid supply pipe 23. The functional component 24 is configured to control the liquid supply tank 22 to stop supplying liquid to the liquid supply pipe 23 and control the cleaning liquid in the liquid supply pipe 23 to flow into at least one of the storage tank 11 and the liquid supply tank 22 when the liquid level in the storage tank 11 reaches a preset liquid level.

[0121] In other words, the cleaning base station 20 stores cleaning fluid through the supply tank 22, and the cleaning base station 10 stores cleaning fluid through the storage tank 11. The cleaning base station 10 cleans the ground with the cleaning fluid in the storage tank 11. When the cleaning fluid in the storage tank 11 is exhausted, the cleaning equipment 10 can move to the cleaning base station 20 and cooperate with it. After the cleaning equipment 10 cooperates with the cleaning base station 20, the supply tank 22 can be connected to the storage tank 11 through the supply pipe 23. That is, the supply pipe 23 can form a connecting flow channel between the supply tank 22 and the storage tank 11, so that the cleaning fluid in the supply tank 22 can be transported to the storage tank 11 to realize the replenishment operation of the storage tank 11. When the liquid level in the storage tank 11 reaches the preset level and it is no longer necessary to continue supplying cleaning fluid to the storage tank 11, the functional component 24 controls the supply tank 22 to stop supplying liquid to the supply pipe 23, thereby stopping the supply of cleaning fluid to the storage tank 11. This prevents the cleaning fluid in the storage tank 11 from overflowing due to exceeding its capacity limit. Furthermore, the functional component 24 controls the cleaning fluid in the supply pipe 23 to flow into at least one of the storage tank 11 and the supply tank 22, that is, to clean and remove the cleaning fluid in the supply pipe 23 through the storage tank 11 and / or the supply tank 22, so as to avoid residual cleaning fluid in the supply pipe 23. This prevents the residual cleaning fluid in the supply pipe 23 from flowing out through the end of the supply pipe 23 away from the supply tank 22 after the cleaning device 10 is separated from the cleaning base station 20, thus avoiding waste or pollution of the surrounding environment. Furthermore, when the end of the supply pipe 23 that is far from the supply tank 22 is in a lower position, the residual liquid in the supply pipe 23 can be drained to avoid the residual liquid in the supply pipe 23 forming a siphon effect, thereby avoiding the waste caused by the supply pipe 23 continuously draining the cleaning liquid in the supply tank 22 under the siphon effect.

[0122] Therefore, by means of functional component 24, when the liquid level in the liquid storage tank 11 reaches the preset liquid level, the cleaning liquid in the liquid supply pipe 23 can be controlled to flow into at least one of the liquid storage tank 11 and the liquid supply tank 22. This can prevent the cleaning liquid remaining in the liquid supply pipe 23 from flowing out through the end of the liquid supply pipe 23 away from the liquid supply tank 22 after the cleaning equipment 10 is separated from the cleaning base station 20, thus avoiding waste or pollution of the surrounding environment. At the same time, it can prevent the liquid remaining in the liquid supply pipe 23 from forming a siphon effect, thereby avoiding the waste caused by the liquid supply pipe 23 continuously discharging the cleaning liquid in the liquid supply tank 22 under the siphon effect.

[0123] It should be noted that when the liquid level in the storage tank 11 reaches the preset liquid level, the functional component 24 can control the cleaning fluid in the supply pipe 23 to flow into the storage tank 11; or the functional component 24 can control the cleaning fluid in the supply pipe 23 to flow into the supply tank 22; or the functional component 24 can control a portion of the cleaning fluid in the supply pipe 23 to flow into the storage tank 11 and another portion to flow into the supply tank 22, without any specific restrictions.

[0124] According to some embodiments of this application, the other end of the liquid supply pipe 23 has a connector 2333 suitable for corresponding to the cleaning device 10. The position of the connector 2333 is lower than the bottom surface of the liquid supply tank 22. That is, the liquid supply tank 22 is located above the connector 2333, so that sufficient space can be reserved below the liquid supply tank 22 for the cleaning device 10 to enter the cleaning base station 20, so as to facilitate cleaning and other operations of the cleaning device 10 in the cleaning base station 20. Furthermore, the connector 2333 is located below the bottom surface of the liquid supply tank 22, which facilitates the docking of the connector 2333 with the cleaning device 10. For example, the connector 2333 can be at approximately the same height as the cleaning device 10, which helps to reduce the difficulty of docking the cleaning device 10 with the connector 2333.

[0125] According to some embodiments of this application, the cleaning device 10 includes a delivery pump 13, which drives the cleaning fluid in the supply tank 22 to be delivered to the storage tank 11 through the supply pipe 23. That is, when the cleaning device 10 cooperates with the cleaning base station 20 and the end of the supply pipe 23 away from the supply tank 22 is connected to the storage tank 11, the delivery pump 13 can deliver the cleaning fluid in the supply tank 22 to the storage tank 11 for storage. This significantly improves the automation level of replenishing the supply tank 22, thereby reducing the user's workload in using the cleaning system 100 and improving the user experience.

[0126] According to some embodiments of this application, the cleaning system 100 has a replenishment mode and a residual liquid discharge mode. In the replenishment mode, the cleaning device 10 cooperates with the cleaning base station 20, and the cleaning fluid in the supply tank 22 is delivered to the storage tank 11 through the supply pipe 23, while the functional component 24 is not working. At this time, the supply tank 22 is connected to the storage tank 11 through the supply pipe 23, so that the cleaning fluid in the supply tank 22 can enter the storage tank 11 through the supply pipe 23 to achieve replenishment. The functional component 24 is not working to avoid affecting the flow of cleaning fluid into the storage tank 11, thereby ensuring the normal progress of the replenishment process. In the residual liquid discharge mode, the cleaning device 10 cooperates with the cleaning base station 20, and the functional component 24 is working. In other words, at this time, the supply pipe 23 is still connected to the storage tank 11, but the cleaning fluid in the supply tank 22 stops flowing into the storage tank 11 through the supply pipe 23. The functional component 24 works to control the flow of the cleaning fluid in the supply pipe 23 into at least one of the storage tank 11 and the supply tank 22, thereby preventing the residual cleaning fluid in the supply pipe 23 from flowing out or causing waste due to the siphon effect.

[0127] According to some embodiments of this application, the functional component 24 includes: a first pump body 241 connected to a liquid supply pipe 23. The first pump body 241 is configured to deliver gas into the liquid supply pipe 23 when the liquid level in the storage tank 11 reaches a preset liquid level, so that the liquid supply tank 22 stops supplying liquid to the liquid supply pipe 23 and the cleaning liquid in the liquid supply pipe 23 flows into at least one of the storage tank 11 and the liquid supply tank 22. That is, when the liquid level in the storage tank 11 reaches the preset liquid level, the gas delivered to the liquid supply pipe 23 by the first pump body 241 can cut off the flow of the cleaning liquid in the liquid supply pipe 23 to the storage tank 11, and at the same time can push the cleaning liquid in the liquid supply pipe 23 toward the storage tank 11 and / or the liquid supply tank 22 to empty the cleaning liquid in the liquid supply pipe 23. Therefore, by using gas to drive the liquid flow, the cleaning fluid in the supply pipe 23 is emptied, which is low-cost and can better avoid introducing other types of liquid into the supply pipe 23, thus improving the reliability of the first pump body 241 in cleaning the cleaning fluid in the supply pipe 23.

[0128] According to some embodiments of this application, the liquid supply pipe 23 includes a first pipe segment 231, a second pipe segment 232, and a third pipe segment 233 connected in sequence. The first pipe segment 231 extends in a vertical direction, and at least a portion of the third pipe segment 233 extends in a vertical direction. The second pipe segment 232 has an angle with both the first pipe segment 231 and the third pipe segment 233. The lower end of the first pipe segment 231 is connected to the liquid supply tank 22. The lower end of the third pipe segment 233 has a connector 2333 suitable for corresponding to the cleaning device 10. The second pipe segment 232 is connected to the upper end of both the first pipe segment 231 and the upper end of the third pipe segment 233. The first pump body 241 is connected to the second pipe segment 232.

[0129] In other words, the first pipe section 231 and the third pipe section 233 are connected through the second pipe section 232. The end of the first pipe section 231 away from the second pipe section 232 is connected to the liquid supply tank 22. The end of the third pipe section 233 away from the second pipe section 232 has a connector 2333. The third pipe section 233 is connected to the cleaning equipment 10 through the connector 2333, thereby achieving the connection between the third pipe section 233 and the liquid storage tank 11. Therefore, in the residual liquid discharge mode, since the first pump body 241 is connected to the second pipe section 232, the first pump body 241 can deliver gas into the second pipe section 232. The gas entering the second pipe section 232 is divided into two parts. One part of the gas flows towards the direction closer to the first pipe section 231, thereby pushing the cleaning liquid located upstream of the connection position between the first pump body 241 and the second pipe section 232 in the liquid supply pipe 23 into the upper end of the first pipe section 231. The first pipe section 231 extends in the vertical direction, so that the liquid in the first pipe section 231 can be propelled by the gas and gravity. The cleaning fluid flows downwards into the supply tank 22 to prevent residue in the first pipe section 231. Another portion of the gas flows towards the third pipe section 233, thereby pushing the cleaning fluid downstream of the connection between the first pump body 241 and the second pipe section 232 into the upper end of the third pipe section 233. At least the portion of the third pipe section 233 connected to the second pipe section 232 extends vertically, allowing the cleaning fluid in the third pipe section 233 to flow downwards into the storage tank 11 under the propulsion of the gas and gravity, thus preventing residue in the third pipe section 233. This improves the cleaning effect on residual cleaning fluid in the supply pipe 23.

[0130] According to some embodiments of this application, the second pipe segment 232 extends in a straight line or is formed into an upwardly curved arc. This effectively prevents cleaning fluid from remaining in the second pipe segment 232 due to downward bending. Furthermore, when the second pipe segment 232 is formed into an upwardly curved arc, meaning that the two ends of the second pipe segment 232 are lower than the middle in the extending direction, any cleaning fluid remaining in the second pipe segment 232 can flow towards both ends of the second pipe segment 232 under the influence of gravity, and further flow into the supply tank 22 and the storage tank 11 through the first pipe segment 231 and the third pipe segment 233 respectively, ensuring that the cleaning fluid in the second pipe segment 232 can be completely drained. In a specific example, the second pipe segment 232 extends in a straight line in the horizontal direction.

[0131] According to some embodiments of this application, the third pipe segment 233 includes a vertical segment 2331 and a connecting segment 2332. The vertical segment 2331 extends vertically and its upper end is connected to the second pipe segment 232. The connecting segment 2332 has an angle with the vertical segment 2331 and has a connector 2333. That is, one end of the connecting segment 2332 is connected to the end of the vertical segment 2331 away from the second pipe segment 232, and the other end of the connecting segment 2332 has a connector 2333 to facilitate docking with the cleaning equipment 10. The cleaning equipment 10 typically moves horizontally into the cleaning base station 20 to cooperate with it. Therefore, the connecting segment 2332, which is angled to the vertical segment 2331, facilitates docking with the connector 2333 on the connecting segment 2332 when the cleaning equipment 10 moves horizontally into the cleaning base station 20, thus reducing the difficulty of docking the connector 2333 with the cleaning equipment 10. In a specific example, the docking section 2332 is set perpendicular to the vertical section 2331, which helps to further reduce the difficulty of docking and fitting the connector 2333 with the cleaning equipment 10.

[0132] According to some embodiments of this application, the functional component 24 is located below the second pipe segment 232 and between the liquid supply tank 22 and the third pipe segment 233. Therefore, the functional component 24 can fully utilize the space below the second pipe segment 232 between the liquid supply tank 22 and the third pipe segment 233, thereby reducing the installation space occupied by the functional component 24 and the liquid supply pipe 23 in the extension direction of the second pipe segment 232, resulting in a compact structure and reasonable layout.

[0133] According to some embodiments of this application, the functional component 24 includes a first connecting pipe 243 and a second connecting pipe 244. The first connecting pipe 243 connects the first pump body 24 to the liquid supply pipe 23, and the second connecting pipe 244 connects to the first pump body 24. The first connecting pipe 243 is connected to the upper side of the first pump body 24, and the second connecting pipe 244 is connected to the lower side of the first pump body 24. That is, the first pump body 241 is connected to the liquid supply pipe 23 through the first connecting pipe 243, and in the vertical direction, the first pump body 241 is connected between the first connecting pipe 243 and the second connecting pipe 244. Therefore, in the residual liquid discharge mode, the first pump body 241 can draw in gas through the second connecting pipe 244 and deliver the gas to the liquid supply pipe 23 through the first connecting pipe 243 to discharge the cleaning liquid in the liquid supply pipe 23. Furthermore, in cleaning mode, the first pump body 241 is connected to the liquid supply tank 22 via the first connecting pipe 243 and the liquid supply pipe 23. Driven by the first pump body 241, liquid in the liquid supply tank 22 can flow through the liquid supply pipe 23, the first connecting pipe 243, the first pump body 241, and the second connecting pipe 244 into the cleaning tank 25 of the cleaning base station 20. This allows the cleaning solution in the cleaning tank 25 to clean the mop 12 of the cleaning device 10. In a specific example, the lower end of the second connecting pipe 244 is located directly above the cleaning tank 25 to ensure reliable delivery of cleaning solution into the cleaning tank 25.

[0134] According to some embodiments of this application, the cleaning device 10 includes a delivery pump 13, which drives the cleaning liquid in the supply tank 22 to be delivered to the storage tank 11 through the supply pipe 23. In the residual liquid discharge mode, the delivery pump 13 does not operate. That is, when the first pump body 241 cleans the cleaning liquid in the supply pipe 23, the delivery pump 13 stops driving the cleaning liquid in the supply tank 22 to be delivered to the storage tank 11 through the supply pipe 23. This effectively prevents the gas delivered to the supply pipe 23 by the first pump body 241 from entering the storage tank 11 through the supply pipe 23, thus preventing the storage tank 11 from being under negative pressure and allowing the cleaning liquid in the supply tank 22 to still enter the storage tank 11 through the supply pipe 23. In other words, it effectively prevents the delivery pump 13 from affecting the first pump body 241's discharge of residual liquid from the supply pipe 23, thereby improving the discharge effect of the functional component 24 on the cleaning liquid in the supply pipe 23.

[0135] According to some embodiments of this application, the cleaning device 10 includes a delivery pump 13, which drives the cleaning fluid in the supply tank 22 to be delivered to the storage tank 11 through the supply pipe 23. In the residual liquid discharge mode, the delivery pump 13 operates and its operating power is less than that of the first pump body 241. Here, "the operating power of the delivery pump 13 is less than the operating power of the first pump body 241" means that the amount of cleaning fluid delivered by the delivery pump 13 per unit time is less than the amount of cleaning fluid that the first pump body 241 can deliver per unit time. Therefore, the delivery pump 13 can only pump a portion of the gas delivered by the first pump body 241 to the liquid supply pipe 23 into the liquid storage tank 11, thereby driving the cleaning liquid located between the gas input position of the first pump body 241 and the liquid storage tank 11 in the liquid supply pipe 23 to flow into the liquid storage tank 11. The remaining gas delivered by the first pump body 241 to the liquid supply pipe 23 can drive the cleaning liquid located between the air input position of the first pump body 241 and the liquid supply tank 22 in the liquid supply pipe 23 to flow into the liquid supply tank 22, so as to clean the residual liquid in the liquid supply pipe 23.

[0136] According to some embodiments of this application, the cleaning base station 20 includes a cleaning component and a cleaning tank 25. The cleaning component includes a second pump body 242, which is connected to a liquid supply tank 22 to deliver cleaning fluid from the liquid supply tank 22 to the cleaning tank 25. Thus, the cleaning device 10 can be cleaned by the cleaning fluid delivered to the cleaning tank 25 by the second pump body 242. When the cleaning device 10 and the cleaning base station 20 are working together, the mopping component 12 of the cleaning device 10 is located in the cleaning tank 25. Therefore, the cleaning fluid in the cleaning tank 25 can effectively remove the dirt and grime that the mopping component 12 picks up during the cleaning process, restoring the cleanliness of the mopping component 12 and improving the cleaning effect of the cleaning device 10 on the surface to be cleaned.

[0137] According to some embodiments of this application, the first pump body 241 and the second pump body 242 are the same pump body, and the cleaning system 100 has a cleaning mode. In the cleaning mode, the first pump body 241 rotates forward, and when the first pump body 241 rotates forward, it is used to deliver the cleaning liquid in the supply tank 22 to the cleaning tank 25, so as to clean the mop 12 located in the cleaning tank 25 through the cleaning liquid in the cleaning tank 25. In the residual liquid discharge mode, the first pump body 241 rotates in reverse, and when the first pump body 241 rotates in reverse, it is used to deliver gas into the supply pipe 23 to clean the cleaning liquid in the supply pipe 23. Thus, by integrating the functions of delivering cleaning liquid into the cleaning tank 25 and delivering gas into the supply pipe 23 into the first pump body 241, the integration of the first pump body 241 can be improved and the second pump body 242 can be saved, thereby reducing the number of parts in the cleaning base station 20, simplifying the structure of the cleaning base station 20 and reducing the manufacturing cost of the cleaning base station 20.

[0138] As shown in Figures 1 to 7, the cleaning system 100 according to an embodiment of this application includes a cleaning device 10 and a cleaning base station 20. The cleaning device 10 includes a pipeline assembly and a first control valve 144. The first control valve 144 is disposed on the pipeline assembly for controlling the pipeline assembly, such as controlling the connection and disconnection of the pipeline assembly. The cleaning device 10 and the cleaning base station 20 can be detachably coupled. The cleaning base station 20 includes a trigger 21. When the cleaning device 10 and the cleaning base station 20 are coupled, the trigger 21 triggers the first control valve 144 to switch to a first state. When the cleaning device 10 and the cleaning base station 20 are disengaged, the first control valve 144 is in a second state, which is different from the first state.

[0139] In other words, the trigger 21 controls the first control valve 144 to switch from the second state to the first state. The first control valve 144 is normally in the second state when not engaged with the trigger 21. When the cleaning device 10 and the cleaning base station 20 are engaged, the trigger 21 automatically engages with the first control valve 144 to switch it from the second state to the first state. When the cleaning device 10 and the cleaning base station 20 are disengaged, the engagement between the trigger 21 and the first control valve 144 is simultaneously released, and the first control valve 144 switches from the first state to the second state after losing the trigger from the trigger 21. That is, the first control valve 144 can automatically switch between the first and second states simply by engaging and disengaging the cleaning device 10 and the cleaning base station 20. This eliminates the need for separate operation of the first control valve 144 to switch between the first and second states, thus improving the efficiency of switching the first control valve 144 between the first and second states.

[0140] According to some embodiments of this application, when the cleaning device 10 and the cleaning base station 20 cooperate, the trigger 21 and the first control valve 144 are arranged opposite to each other. This reduces the difficulty of cooperating between the trigger 21 and the first control valve 144, and improves the stability of the trigger 21 triggering the first control valve 144. In a specific example, the trigger 21 and the first control valve 144 are arranged opposite to each other along the cooperation direction of the cleaning device 10 and the cleaning base station 20.

[0141] According to some embodiments of this application, one of the first state and the second state is a conducting state and the other is a cut-off state. Thus, by cooperating and separating the cleaning device 10 and the cleaning base station 20, the first control valve 144 can be switched between the conducting state and the cut-off state. When the first control valve 144 is in the conducting state, it can connect the channels on both sides, allowing substances in the channel on one side of the first control valve 144 to enter the channel on the other side of the first control valve 144. When the first control valve 144 is in the cut-off state, the connection between the channels on both sides of the first control valve 144 is cut off, preventing substances in the channel on one side of the first control valve 144 from entering the channel on the other side of the first control valve 144.

[0142] According to some embodiments of this application, the cleaning device 10 includes a liquid storage tank 11 and a delivery pump 13. The pipeline assembly includes a first pipeline assembly, which is connected to both the liquid storage tank 11 and the delivery pump 13. A first control valve 144 is disposed on the first pipeline assembly for controlling the first pipeline assembly. The cleaning base station 20 includes a supply tank 22, which is in a first state of conduction and in a second state of cutoff. When the cleaning device 10 and the cleaning base station 20 cooperate, the delivery pump 13 is used to deliver the substance in the supply tank 22 to the liquid storage tank 11 through the first pipeline assembly.

[0143] In other words, when the cleaning equipment 10 and the cleaning base station 20 are working together, the supply tank 22 can be connected to the storage tank 11 through the first pipeline assembly, and the first control valve 144 is in the conducting state after being triggered by the trigger 21, so that the delivery pump 13 can be connected to the supply tank 22 through the first pipeline assembly. Therefore, when the delivery pump 13 is running, such as during the suction action, it can apply pressure to the material in the supply tank 22 so that the material in the supply tank 22 can enter the storage tank 11 along the first pipeline assembly, thereby realizing the operation of replenishing the material in the storage tank 11. After the cleaning equipment 10 and the cleaning base station 20 are separated, the first pipeline assembly is disconnected from the supply tank 22, and the first control valve 144 is disengaged from the trigger 21 and switched to the cut-off state.

[0144] According to some embodiments of this application, the first control valve 144 includes a valve core 1441, which is movable between an on position and a off position. When the cleaning device 10 cooperates with the cleaning base station 20, the trigger 21 exerts a force on the valve core 1441 to drive the valve core 1441 to move to the on position. In the on position, the first control valve 144 is in an on state, and in the off position, the first control valve 144 is in an off state. That is, by moving the valve core 1441 between the on and off positions, the first control valve 144 is switched between the on and off states. The trigger 21 directly cooperates with the valve core 1441 to drive the valve core 1441 to move, which reduces the difficulty of triggering the first control valve 144 to switch to the on state and simplifies the structure of the first control valve 21.

[0145] According to some embodiments of this application, the first control valve 144 includes an elastic reset member 1442. One end of the elastic reset member 1442 is connected to the first pipeline assembly and the other end is connected to the valve core 1441. The elastic reset member 1442 is used to drive the valve core 1441 to move to the cut-off position. That is, the elastic reset member 1442 has a tendency to drive the valve core 1441 to move toward the cut-off position. Therefore, when the cleaning device 10 is separated from the cleaning base station 20, the valve core 1441 is usually in the cut-off position under the action of the elastic reset member 1442. When the cleaning device 10 and the cleaning base station 20 cooperate, the force between the trigger member 21 and the valve core 1441 drives the valve core 1441 to overcome the elastic force of the elastic reset member 1442, so that the valve core 1441 moves from the cut-off position toward the conduction position, thereby switching the first control valve 144 to the conduction state. When the cleaning device 10 disengages from the cleaning base station 20, the force between the trigger 21 and the valve core 1441 disappears. That is, the force acting on the valve core 1441 to compress the elastic reset member 1442 disappears, and the elastic reset member 1442 recovers its elastic deformation to drive the valve core 1441 from the conducting position to the cut-off position, thereby switching the first control valve 144 to the cut-off state. Thus, through the cooperation of the valve core 1441, the elastic reset member 1442, and the trigger 21, the first control valve 144 can be effectively switched to the conducting state when the cleaning device 10 and the cleaning base station 20 are engaged, and to the cut-off state after the cleaning device 10 and the cleaning base station 20 are separated. This ensures the stability of the first control valve 144 in switching between the conducting and cut-off states.

[0146] According to some embodiments of this application, a magnetic force exists between the trigger 21 and the valve core 1441 to drive the valve core 1441 to the conducting position. That is, after the cleaning device 10 and the cleaning base station 20 cooperate, a mutually attractive magnetic force is formed between the trigger 21 and the valve core 1441, causing the trigger 21 and the valve core 1441 to tend to move closer together. Since the trigger 21 is located on the cleaning base station 20, the valve core 1441, under the action of the magnetic force, squeezes the elastic reset member 1442 and moves towards the trigger 21 until it is in the conducting position. When the cleaning device 10 and the cleaning base station 20 disengage, the magnetic force between the trigger 21 and the valve core 1441 disappears, that is, the compression thrust of the valve core 1441 on the elastic reset member 1442 disappears, and the elastic reset member 1442 restores its elastic deformation, driving the valve core 1441 to move from the conducting position to the cut-off position. Therefore, by using the magnetic cooperation between the trigger 21 and the valve core 1441 to move the valve core 1441 from the conducting position to the cut-off position, the positioning difficulty between the trigger 21 and the valve core 1441 can be reduced. At the same time, the cooperation structure between the trigger 21 and the valve core 1441 can be simplified, which helps to reduce the difficulty of the trigger 21 triggering the first control valve 144.

[0147] According to some embodiments of this application, at least a portion of the trigger 21 is made of a magnet, and at least a portion of the valve core 1441 is made of a ferromagnetic material. The magnet can attract the ferromagnetic material; that is, the magnetic portion of the trigger 21 attracts the ferromagnetic portion of the valve core 1441, creating a magnetic force between the trigger 21 and the valve core 1441. This ensures that when the cleaning device 10 and the cleaning base station 20 cooperate, the trigger 21 can attract the valve core 1441 towards the direction closer to the trigger 21, i.e., towards the conduction position, so that the first control valve 144 switches to the conduction state. It should be noted that the trigger 21 may be partially or entirely made of a magnet; similarly, the valve core 1441 may be partially or entirely made of a ferromagnetic material; no specific limitations are imposed here.

[0148] According to some embodiments of this application, the trigger 21 is a magnet, and the valve core 1441 is made of steel. This reduces the cost of the trigger 21 and the valve core 1441, while the durability of steel improves the service life of the valve core 1441. It should be noted that this is merely an example illustrating one specific material of the trigger 21 and the valve core 1441 to facilitate understanding of their fit; it is not a limitation on the materials of the trigger 21 and the valve core 1441. The materials of the trigger 21 and the valve core 1441 only need to allow them to exert a force that brings them closer together.

[0149] According to some embodiments of this application, the valve core 1441 is formed in a spherical shape. Therefore, by setting the valve core 1441 to a spherical shape, it is easier for the valve core 1441 to roll within the first piping assembly, while also better preventing positional displacement of the valve core 1441 within the first piping assembly, which helps to improve the stability and reliability of the first control valve 144.

[0150] According to some embodiments of this application, the cleaning base station 20 includes a liquid supply pipe 23, one end of which is connected to the liquid supply tank 22 and the other end has a connector 2333. The first pipeline assembly has a mating interface 1411. When the cleaning equipment 10 and the cleaning base station 20 cooperate, the connector 2333 is adapted to be inserted into the mating interface 1411. That is, the liquid supply pipe 23 is adapted to be inserted and cooperated with the first pipeline assembly. The cooperation method is simple and easy to connect and disconnect. When the cleaning equipment 10 and the cleaning base station 20 cooperate, the liquid supply pipe 23 is connected to the first pipeline assembly through the insertion and cooperation of the connector 2333 and the mating interface 1411. Thus, through the connection between the liquid supply pipe 23 and the first pipeline assembly, a material supply channel is formed between the liquid supply tank 22 and the storage tank 11. This allows the material in the liquid supply tank 22 to enter the storage tank 11 through the portion of the liquid supply pipe 23 and the first pipeline assembly connected by the delivery pump 13.

[0151] According to some embodiments of this application, the trigger 21 is located above the connector 2333. That is, when the cleaning device 10 and the cleaning base station 20 are working together, the mating position of the trigger 21 and the first control valve 144 is located above the insertion position of the connector 2333 and the interface 1411. This effectively avoids the leakage at the connection point between the connector 2333 and the interface 1411 affecting the mating of the trigger 21 and the first control valve 144, ensuring that the trigger 21 can stably trigger the first control valve 144 to the first state when the cleaning device 10 and the cleaning base station 20 are working together, thus improving the stability of the mating between the trigger 21 and the first control valve 144.

[0152] According to some embodiments of this application, the other end of the liquid supply pipe 23 has a connector 2333 suitable for corresponding to the cleaning device 10. The position of the connector 2333 is lower than the bottom surface of the liquid supply tank 22. That is, the liquid supply tank 22 is located above the connector 2333, so that sufficient space can be reserved below the liquid supply tank 22 for the cleaning device 10 to enter the cleaning base station 20, so as to facilitate cleaning and other operations of the cleaning device 10 in the cleaning base station 20. Furthermore, the connector 2333 is located below the bottom surface of the liquid supply tank 22, which facilitates the docking of the connector 2333 with the cleaning device 10. For example, the connector 2333 can be at approximately the same height as the cleaning device 10, which helps to reduce the difficulty of docking the cleaning device 10 with the connector 2333.

[0153] According to some embodiments of this application, the first control valve 144 and the interface 1411 are located on the same side of the cleaning device 10. This reduces the difficulty of coordinating the interface 1411 and the first control valve 144 with the cleaning base station 20.

[0154] According to some embodiments of this application, the first pipeline assembly includes a liquid inlet pipeline 141, an air extraction pipeline 142, and an exhaust pipeline 143. One end of the liquid inlet pipeline 141 is connected to the liquid storage tank 11, and the other end forms a docking interface 1411 for docking with the cleaning base station 20. One end of the air extraction pipeline 142 is connected to the liquid storage tank 11, and the other end is connected to the inlet of the delivery pump 13. The exhaust pipeline 143 is connected to the outlet of the delivery pump 13. A first control valve 144 is disposed on the air extraction pipeline 142. That is, when the cleaning equipment 10 and the cleaning base station 20 cooperate, the liquid inlet pipeline 141 docks with the cleaning base station 20 through the docking interface 1411 to communicate with the liquid supply tank 22, thereby forming a connected material transport channel between the liquid supply tank 22 and the liquid storage tank 11 through the liquid inlet pipeline 141. The delivery pump 13 is connected to the storage tank 11 via the suction pipe 142 and is connected between the suction pipe 142 and the exhaust pipe 143. Therefore, the delivery pump 13 can extract the gas in the storage tank 11 through the suction pipe 142 and discharge it through the exhaust pipe 143. The first control valve 144 is located in the suction pipe 142 to control the opening and closing of the suction pipe 142, thereby controlling the connection or disconnection of the delivery pump 13 with the storage tank 11 through the suction pipe 142. Thus, the delivery pump 13 can drive the substance in the supply tank 22 into the storage tank 11 through the cooperation of the inlet pipe 141, the suction pipe 142, the exhaust pipe 143, and the first control valve 144.

[0155] Specifically, when the cleaning equipment 10 cooperates with the cleaning base station 20, the liquid inlet pipe 141 is connected to the cleaning base station 20 via the interface 1411 to connect with the liquid supply tank 22. At this time, the liquid supply tank 22 is connected to the storage tank 11 via the liquid inlet pipe 141. The trigger 21 triggers the first control valve 144 to be in the conducting state, which makes the air extraction pipe 142 in the conducting state. The inlet of the delivery pump 13 is connected to the storage tank 11 via the air extraction pipe 142. Therefore, the delivery pump 13 can expel the gas in the storage tank 11 through the air extraction pipe 142. The gas is extracted and discharged through the exhaust pipe 143. As the gas in the storage tank 11 is continuously discharged, the gas pressure in the storage tank 11 also decreases. That is, the delivery pump 13 can draw negative pressure into the storage tank 11. Since a material delivery channel is formed between the supply tank 22 and the storage tank 11, a pressure difference can be formed between the supply tank 22 and the storage tank 11. Therefore, the material in the supply tank 22 can enter the storage tank 11 through the inlet pipe 141 under the action of the pressure difference, so as to realize the operation of replenishing the storage tank 11.

[0156] According to some embodiments of this application, as shown in Figures 5 and 6, an air extraction channel 1421 is formed within the air extraction pipe 142. A portion of the outer peripheral wall of the air extraction pipe 142 protrudes outward to form a bulge 1422. A receiving cavity 1423 communicating with the air extraction channel 1421 is formed within the bulge 1422. The first control valve 144 includes a valve core 1441, which is movable between a conducting position and a cut-off position. The trigger 21 is adapted to apply a force to the valve core 1441 to drive it to the conducting position. In the conducting position, the valve core 1441 is located within the receiving cavity 1423 and conducts the air extraction channel 1421, and the first control valve 144 is in a conducting state. In the cut-off position, at least a portion of the valve core 1441 is located within the air extraction channel 1421 and blocks the air extraction channel 1421, and the first control valve 144 is in a cut-off state. Therefore, the valve core 1441 in the conducting position can be well housed by the receiving cavity 1423, thereby avoiding the valve core 1441 from being located in the air extraction channel 1421 and causing resistance to the flow of gas, which is conducive to improving the efficiency of the delivery pump 13 in discharging gas from the storage tank 11.

[0157] According to some embodiments of this application, the first control valve 144 includes an elastic reset member 1442, which is located within the receiving cavity 1423. One end of the elastic reset member 1442 is connected to the protrusion 1422, and the other end is connected to the valve core 1441. The elastic reset member 1442 is used to drive the valve core 1441 to move to the cut-off position. Therefore, by placing the elastic reset member 1442 within the receiving cavity 1423, the obstruction of airflow within the suction channel 1421 by the elastic reset member 1442 can be effectively avoided, thereby reducing the gas flow resistance within the suction pipeline 142 and improving the efficiency of the delivery pump 13 in discharging gas from the storage tank 11.

[0158] According to some embodiments of this application, both the supply tank 22 and the storage tank 11 are used to store cleaning fluid. The cleaning base station 20 includes a supply pipe 23 and a functional component 24. The functional component 24 is configured to control the supply tank 22 to stop supplying fluid to the supply pipe 23 and control the cleaning fluid in the supply pipe 23 to flow into at least one of the supply tank 22 and the storage tank 11 when the liquid level in the storage tank 11 reaches a preset liquid level. At this time, the supply tank 22 is connected to the storage tank 11 through the supply pipe 23. Under the drive of the delivery pump 13, the cleaning fluid in the supply tank 22 enters the storage tank 11 through the supply pipe 23, thereby realizing the operation of replenishing the storage tank 11. In the residual liquid discharge mode, the cleaning device 10 cooperates with the cleaning base station 20, and the functional component 24 works. At this time, the liquid supply pipe 23 is still connected to the liquid storage tank 11, but the cleaning liquid in the liquid supply tank 22 stops flowing into the liquid storage tank 11 through the liquid supply pipe 23. The functional component 24 works to control the flow of the cleaning liquid in the liquid supply pipe 23 into at least one of the liquid storage tank 11 and the liquid supply tank 22, thereby preventing the residual cleaning liquid in the liquid supply pipe 23 from flowing out or causing waste due to the siphon effect.

[0159] The cleaning system 100 according to a specific embodiment of this application is described below with reference to Figures 1-7. It is to be understood that the following description is exemplary only and is intended to explain this application, and should not be construed as limiting this application.

[0160] The cleaning system 100 includes a cleaning device 10 and a cleaning base station 20. The cleaning device 10 includes a liquid storage tank 11, a mopping component 12, a delivery pump 13, a first piping assembly, a second piping assembly, and a level sensor. The level sensor is located inside the liquid storage tank 11 to detect the level of the cleaning liquid within the tank. The first piping assembly includes an inlet pipe 141, an exhaust pipe 142, and an exhaust pipe 143. One end of the inlet pipe 141 is connected to the liquid storage tank 11, and the other end forms a connection port 1411.

A first control valve 144 is provided on the gas pipeline 142. The first control valve 144 includes a valve core 1441 and an elastic reset member 1442. The valve core 1441 is made of steel. Under the action of the elastic reset member 1442, the valve core 1441 is in the cut-off position to cut off the gas extraction pipeline 142.

The first control valve 144 is located above the first connection position, and the third connection position is located above the second connection position.

[0161] The cleaning base station 20 includes a trigger 21, a liquid supply tank 22, a liquid supply pipe 23, a functional component 24, and a cleaning tank 25. The liquid supply tank 22 is located above the cleaning tank 25. The liquid supply pipe 23 includes a first pipe section 231, a second pipe section 232, and a third pipe section 233. The first pipe section 231 extends vertically, the second pipe section 232 extends horizontally, and the third pipe section 233 includes a vertical section 2331 extending vertically and a connecting section 2332 extending horizontally. The lower end of the first pipe section 231 is connected to the liquid supply tank 22. The upper end of the first pipe section 231 is connected to one end of the second pipe section 232, the other end of the second pipe section 232 is connected to the upper end of the vertical section 2331, the lower end of the vertical section 2331 is connected to one end of the docking section 2332, and the other end of the docking section 2332 has a connector 2333. The connector 2333 is located below the bottom surface of the liquid supply tank 22 and is suitable for separable engagement with the interface 1411. The trigger 21 is located above the connector 2333 and opposite to the first control valve 144. The trigger 21 is a magnetic element. Functional component 24 is located below the second pipe section 232 and between the liquid supply tank 22 and the third pipe section 233. Functional component 24 includes a first pump body 241, a second pump body 242, a first connecting pipe 243 and a second connecting pipe 244. The first pump body 241 and the second pump body 242 are the same pump body, and the first pump body 241 can rotate forward and reverse to drive the fluid in two directions. The upper end of the first connecting pipe 243 is connected to the middle of the second pipe section 232. The first pump body 241 is connected to the lower end of the first connecting pipe 243 and the upper end of the second connecting pipe 244. The lower end of the second connecting pipe 244 is located directly above the cleaning tank 25.

[0162] Specifically, the cleaning system 100 has a replenishment mode, a residual liquid discharge mode, a cleaning mode, and a rinsing mode.

[0163] In the replenishment mode, the cleaning device 10 returns to the cleaning base station 20 and cooperates with the cleaning base station 20. At this time, the connector 2333 is connected to the interface 1411, the supply pipe 23 is connected to the inlet pipe 141, the trigger 21 attracts the valve core 1441 to squeeze the elastic reset member 1442 and move it to the conduction position. At this time, the suction pipe 142 is in the conduction state, the first pump body 241 is controlled to close and the delivery pump 13 is controlled to open. The delivery pump 13 discharges the gas in the storage tank 11 through the suction pipe 142 and the exhaust pipe 143, and a negative pressure is formed in the storage tank 11. The cleaning liquid in the supply tank 22 enters the storage tank 11 along the supply pipe 23 and the inlet pipe 141 under the action of the pressure difference on both sides until the cleaning liquid in the storage tank 11 reaches the preset liquid level.

[0164] In the residual liquid discharge mode, when the cleaning liquid in the storage tank 11 reaches the preset level, the control delivery pump 13 is turned off and the first pump body 241 is reversed, thereby delivering gas to the second pipe section 232 through the second connecting pipe 244 and the first connecting pipe 243. The gas entering the second pipe section 232 is divided into two streams flowing towards the supply tank 22 and the storage tank 11, thereby pushing the liquid in the supply pipe 23 into the supply tank 22 and the storage tank 11 until the residual liquid in the supply pipe 23 is completely discharged.

[0165] In cleaning mode, the control delivery pump 13 is turned off and the first pump body 241 is controlled to rotate forward. The first pump body 241 drives the cleaning liquid in the supply tank 22 to be delivered to the cleaning tank 25 through the supply pipe 23 located between the supply tank 22 and the first connecting pipe 243, the first connecting pipe 243 and the second connecting pipe 244, so as to clean the mop 12 located in the cleaning tank 25 with the cleaning liquid in the cleaning tank 25.

[0166] In cleaning mode, the cleaning device 10 is separated from the cleaning base station 20, the force of the trigger 21 acting on the valve core 1441 disappears, and the valve core 1441 is reset to the cut-off state under the push of the elastic reset member 1442 to cut off the air extraction pipe 142, and the control delivery pump 13 is turned on. Under the drive of the delivery pump 13, the cleaning liquid in the storage tank 11 is delivered to the mopping member 12 through the liquid extraction pipe 151 and the liquid discharge pipe 152 to wet the mopping member 12, so that the mopping member 12 can mop the surface to be cleaned.
